Signal integrity or SI is a set of measures of the quality of an electrical signal. In digital electronics, a stream of binary values is represented by a voltage (or current) waveform. However, digital signals are fundamentally analog in nature, and all signals are subject to effects such as noise, distortion, and loss. Over short distances and at low bit rates, a simple conductor can transmit this with sufficient fidelity. At high bit rates and over longer distances or through various mediums, various effects can degrade the electrical signal to the point where errors occur and the system or device fails.

Signal integrity engineering is the task of analyzing and mitigating these effects. Signal integrity engineering is an important activity at all levels of electronics packaging and assembly, from internal connections of an integrated circuit (IC), through the package, the printed circuit board (PCB), the backplane, and inter-system connections. While there are some common themes at these various levels, there are also practical considerations, in particular the interconnect time versus the bit period, that cause substantial differences in the approach to signal integrity for on-chip connections versus chip-to-chip connections.


KPTronix hardware design team is capable of:
• High Speed Signals/Circuit Simulations
• Simulation using Spice and IBIS Models
• Transmission Models with Electrical Characteristics
• Serpentine Track for Length Matching
• Impedance Matching for maximum power transmission
• Delay Matching for Timing especially for DDR Memories

Our design activities include decoupling design involving capacitor placement and selection (dielectric types, body sizes and values), via placement, capacitor landing pad design, ferrite bead selection, design of Pi filters to create quiet power for PLL/DLL/Clock oscillator circuits, and the design and analysis of power islands/power splits.

 

A shortened time to market, often limits the amount of product testing that can be performed. Microprocessor-based products released with unstable memory may experience only intermittent failures, but even those can lead to a costly recall. To minimize that risk, comprehensive memory timing analysis need to be performed during the design phase of the product.

Net topologies, trace impedances and terminations play an important role in waveform integrity. Trace length, vias and cross talk play an important role in timing.. A combined signal integrity analysis and timing analysis environment is needed to guarantee proper function of the DDR interface.

JEDEC timing requirements

In the JESD79 and JESD208 documents, more information can be found about the different DDRx specification. Thorough knowledge of the different timing parameters within a DDRx device is mandatory for performing detailed accurate timing analysis. By using high-speed design, analysis and verification techniques early in the design cycle, designers can eliminate layout iterations and ensure that products are marketed on time.

 
 

Designers are creating Printed Circuit Boards (PCBs) with higher density, higher power and smaller than ever before. Thermal analysis is necessary to keep up with these advances. To realize and solve potential problems in the design phase and avoid costly overdesign or failure due to thermal issues, thermal analyses must be performed. At KPTronix we offer thermal analysis :
